The coffee industry plays a major role in the global economy. It also has a significant impact on the environment, producing more than 2 billion tonnes of coffee by-products annually. Coffee silverskin (the epidermis of the coffee bean) is usually removed during processing, after the beans have been dried, while the coffee grounds are normally directly discarded.It has traditionally been assumed that these by-products \u2500 coffee grounds and coffee silverskin, have few practical uses and applications. Spent coffee grounds are sometimes employed as homemade skin exfoliants or as abrasive cleaning products. They are also known to make great composting agents for fertilizing certain plants. But apart from these limited applications, coffee by-products are by and large deemed to be virtually useless. As such, practically all of this highly contaminating \u2018coffee waste\u2019 ends up in landfills across the globe and has a considerable knock-on effect on the environment.<\/p>\n","protected":false},"author":0,"featured_media":0,"template":"","meta":{"_acf_changed":false,"footnotes":"","_links_to":"","_links_to_target":""},"class_list":["post-303938","news","type-news","status-publish","hentry"],"acf":[],"yoast_head":"\n
